that's what it's all about. you need to look closely at the switch
to make sure it's understanding .1q and that the router port is
set up as a trunk. you may have to force that if it's wanting to
use some kind of protocol to set up it's trunking & vlans.
the other thing to watch is that you've set up your address on
a sub-interface, since traffic that goes out over the main
interface will be untagged and at the mercy of the switches
handling for untagged traffic on that port, which might be to
flood, drop or do old-fashioned switch things...
